ALBERT HOLBROOK, OF PROVIDENCE, RHODE ISLAND.

PICKER.

Specification of Letters Patent No. 32,770, dated July 9, 1861.

To all whom fit 'may concern:

lle it known that l, ALBERT HoLBaoort, of the city and count-y of Providence and State of Rhode Island, have invented a new and useful lmproveinent in Applying Pickers to Picker-Staffs; and l do hereby declare the saine to be fully described .in the following specification and illustrated in the ac companying drawings, of which- Figure l, denotes a rear end elevation of a picker statt' as constructed in accordance with my invention; Fig. 2, a vertical and longitudinal section of the same; Fig. 3, a side view of the spring.

The nature of my invention consists in dispensing with the use of screws nails ctc., and coniining the picker to the picker staff by means of a spring formed and applied to the said stati', and operating with a slot in the said picker in manner as will be hereinafter set forth.

lt a fact well known that an easy, simple and effective method of applying a box picker to a picker staff and detaching it therefrom as circumstances may require, is a desideratuln which has long existed. The usual 1 actice of confining the picker to the staff by means of screws nails &c. is very objectionable as by the concussion or vibration of the picker the heads of the nails or screws soon commence wearing upon the picker and render it loose, and besides the nails or screws driven into the picker statt weaken it often causing it to split.

My object in inventing my improvement has been to remedy these evils and this l do by dispensing with the use of nails or screws and employing a spring in lieu thereof.

In the drawings A, denotes the top part of a picker staff the same having a bent spring B, attached to its back side and eX- tending down a short distance as seen in Fig. 2. The lower part of the spring` is bent at a right angle or thereabout to the main part so as to forni a catch a, to operate in connection with a slot c, formed transversely of the picker in manner as shown in F ig. l. such an application or arrangement of the spring with respect to the picker the latter is held tirnily in place without danger of becoming loose as is often the case when the picker is applied to the stall' by m mns of screws or nails.

lrly iinprrweinent is not only very simple but it enables a picker to be readily attadnea` to the staff or detached therefrom without any liability of injuring it.

O, is a leather wedge which is placed between the picker and statt' the same being not only for the purpose of maintaining a proper tension of the spring, butto prevent the front part of the picker statt from injury.

l do not claim broadly applying a rawhide picker to a picker staff, but l claim my improved inode of applying it viz. by means of a spring lever provided with acatch a., operating with the slot 0, of the picker in manner as represented and for the purpose set forth.

ALBERT HOLE OOli.
